OK, but now the patch assumes that it's a mutable output, so the auto-mute shall happen.

Actually other OSes seem to mute the line-out as well, so we may follow the standard scenario.

OK, so I guess the bit in the distribution that saves and restores mixer settings at shutdown/startup needs updating to take this new mixer into account? as the speaker mixer is always muted at startup now.

Right, it's the user-space stuff.  The recent alsactl should do it right (adjust to the certain level for new control elements), I thought.

Anyway, I'm inclined to revert the change once after figuring out what caused the issue on Emmanuel's machine.

Hi Takashi,

Sorry for the few days of silence. Attached is the output from your latest patch with the debug patch.

Just one more thing (in case it may help), the output is not really muted, there are some very short sounds/plops randomly appearing between periods of silence when playing a file.

Hrm, the alsa-info output still shows the unexpected pin-cfg setup. But, this is a slightly different topic from the other mixer issues, so let's keep tracking this in another thread.

Meanwhile, I reverted the affecting commit now and merged to sound git tree. It'll be included in the next pull request for 2.6.39-rc.

thanks,

Takashi
